Figure 4-35. A500: show switch circuit screen
The pp VBRnrt (Variable Bit Rate) virtual circuits between A500 ports A1.1
(PPN) and A1.2 (EPN) are used for signaling between the PPN and each
EPN.
These are established once upon initialization under control of S8700
Multi-Connect call processing. They represent the ATM Control Link (ACL)
and Expansion Archangel Link (EAL).
VBRnrt virtual circuits are also be used for ISDN channels between S8700
Multi-Connect port networks.
Other VBRnrt virtual circuits may exist between A500 ports that are not
associated with S8700 Multi-Connect port networks. A common use of
VBRnrt circuits is multimedia and video-conferencing systems.
CaPro Layer
Are talk paths being established between port networks?
Diagnostics
Can you talk both ways on a set on one port network dialed from another
port network, and vice versa?
1. Enter show switch circuit on the A500 console.
